A common feminist misinfo misrepresents recent paternal age birth risk research.
Comparing ages 20s vs 50s, Dads have tiny absolute risk increases (~1%-3%) for non-fatal risks like ADHD/autism, but Moms have largest absolute risk increases for fatal risks like miscarriage (~11%-50%+).
Evolution (having offspring) tolerates the tiny rise of nonfatal birth risks in older fathers but not the large rise of fatal birth risks in older mothers. Which is reflected in traditional lindy gender/age pairing differences.

the average american father in 1970 was 27.
now he's 32.
fathers over 50 double the autism risk in their kids (2.2x, controlling for maternal age), 14% more NICU admissions, 14% more preterm births, 18% more seizures.
